Mas quando se checa _benchmarks_ e comparações você deveria ter o seguinte em mente.

  - type: input
    id: author-other-languages-experience
    attributes:
      label: "Other Languages Experience"
      description: "What other languages do you have experience with?"
      placeholder: "Go, Python, JS, Rust"
    validations:
      required: false

  - type: checkboxes
    id: related-idea
    attributes:
      label: "Related Idea"
      options:

Do đó bạn có thể quay lại và tìm chính xác những gì bạn cần.

## Chạy mã

Tất cả các code block có thể được sao chép và sử dụng trực tiếp (chúng thực chất là các tệp tin Python đã được kiểm thử).

Để chạy bất kì ví dụ nào, sao chép code tới tệp tin `main.py`, và bắt đầu `uvicorn` với:

<div class="termy">

```console
$ uvicorn main:app --reload

* など

それでも、例えば本番環境のような特定の環境のみで、あるいは環境変数の設定によってAPIドキュメントをどうしても無効にしたいという、非常に特殊なユースケースがあるかもしれません。

## 設定と環境変数による条件付き OpenAPI

生成するOpenAPIとドキュメントUIの構成は、共通のPydanticの設定を使用して簡単に切り替えられます。

例えば、

```Python hl_lines="6  11"
{!../../docs_src/conditional_openapi/tutorial001.py!}
```

ここでは `openapi_url` の設定を、デフォルトの `"/openapi.json"` のまま宣言しています。

そして、これを `FastAPI` appを作る際に使います。

## Hypercorn ⏮️ 🎻

💃 &amp; **FastAPI** ⚓️ 🔛 <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>, ❔ ⚒ 👫 🔗 ⏮️ 👯‍♂️ 🐍 🐩 🗃 <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">✳</a> &amp; <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">🎻</a>.

    * Unless it's a feature we want to discourage, like support for a corner case that we don't want users to use.
* The docs should include a source example file, not write Python directly in Markdown.
* If the source example(s) file can have different syntax for Python 3.8, 3.9, 3.10, there should be different versions of the file, and they should be shown in tabs in the docs.
* There should be tests testing the source example.

    Read more about it in the
    [FastAPI docs for Bigger Applications - Multiple Files](https://fastapi.tiangolo.com/tutorial/bigger-applications/).

    ## Example

    ```python
    from fastapi import APIRouter, FastAPI

    app = FastAPI()
    router = APIRouter()


    @router.get("/users/", tags=["users"])
    async def read_users():

# Using Dataclasses

FastAPI is built on top of **Pydantic**, and I have been showing you how to use Pydantic models to declare requests and responses.

But FastAPI also supports using <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a> the same way:

{* ../../docs_src/dataclasses/tutorial001.py hl[1,7:12,19:20] *}

* 노마드 같은 다른 도구로 배포하기
* 여러분의 컨테이너 이미지를 배포해주는 클라우드 서비스로 배포하기

## Poetry의 도커 이미지

만약 여러분들이 프로젝트 의존성을 관리하기 위해 <a href="https://python-poetry.org/" class="external-link" target="_blank">Poetry</a>를 사용한다면, 도커의 멀티-스테이지 빌딩을 사용할 수 있습니다:

```{ .dockerfile .annotate }
# (1)
FROM python:3.9 as requirements-stage

# (2)
WORKDIR /tmp

# (3)
RUN pip install poetry

# (4)

}

function cidr_to_ips() {
    CIDR="$1"
    # cidr_to_ips returns a list of single IPs from a CIDR. We skip 1000 (since they are likely to be allocated
    # already to other services), then pick the next 100.
    python3 - <<EOF
from ipaddress import ip_network, IPv6Network;
from itertools import islice;

net = ip_network('$CIDR')
net_bits = 128 if type(net) == IPv6Network else 32;
net_len = pow(2, net_bits - net.prefixlen)
